The bond between atoms with sharply different electronegativities. In strict terms, an ionic bond refers to the electrostatic attraction experienced between the electric charges of a @[email protected] and an @[email protected], in contrast with a purely @[email protected] In practice, it is preferable to consider the amount of ionic character of a bond rather than referring to purely ionic or purely covalent bonds. The relationship was proposed (L. Pauling) for the estimation of ionic character of a bond between atoms A and B: $\text{Amount of ionic character} = 1 - e^{-1/4}\ (\chi _{\text{A}}\,-\,\chi_{\text{B}})$ where $$\chi _{\text{A}}$$ and $$\chi _{\text{B}}$$ are the Pauling @[email protected] of atoms A and B. This type of bonding is realized mostly in solids.
